  A freezing room 5 is located under the vegetable room 4 at the bottom of the refrigerator 1. A freezer compartment door 9 that freely opens and closes the front opening of the freezer compartment 5 is attached.

  A machine room 19 is located outside the lowermost rear side of the refrigerator 1. The machine room 19 is provided with a compressor 15 which is a main component of the refrigeration cycle. The compressor 15 sucks low-temperature / low-pressure refrigerant gas, compresses it into a high-temperature / high-pressure refrigerant gas, and discharges the refrigerant gas to the high-pressure side of the refrigeration cycle.

  On the back side of the refrigerator 1, a cooler chamber 18 is located above the machine chamber 19. The cooler chamber 18 is provided with a cooler 16 that generates heat by exchanging heat between refrigerant and air in the refrigeration cycle, and a blower 17 that forcibly circulates the cool air to each part in the refrigerator.

  In order to circulate the cool air from the cooler chamber 18 to each chamber, an air passage is formed. FIG. 1 shows a rear duct 31 that faces the refrigerator compartment 2 in the air passage. The cool air (indicated by an arrow in FIG. 1) blown to the back duct 31 is blown out from the back of the refrigerating chamber 2 to the refrigerating chamber 2. A part of the cool air in the rear duct 31 is diverted, and the rear side of the pair of shelf support portions 22 (two on the left and right sides of the refrigerator compartment 2 and the rails for moving the shelf) that support the food storage shelf 13 ( It flows through a space (air passage) between the shelf support portion 22 and the inner box 1a (between the side walls of the refrigerator compartment 2). Further, the cold air is blown out to the refrigerating chamber 2 in the front-rear direction from an outlet part 21 formed long in the vertical direction with respect to the refrigerating chamber 2. The cold air blown forward from the outlet part 21 cools the food stored in the door food storage pocket 10 of the refrigerator compartment door 6. Further, the cold air blown out backward from the outlet part 21 cools the food stored in the food storage shelf 12, the food storage shelf 13, the food storage shelf 14, and the like.

  There are two shelf support portions 22 for supporting the food storage shelf 13 on the left and right side surfaces of the refrigerator compartment 2. There are also two outlet parts 21 connected to the shelf support part 22 at the front part of the left and right side surfaces of the refrigerator compartment 2. Therefore, the cold air from the rear duct 31 flows through these two paths and is blown out from the two outlet parts 21 into the refrigerator compartment 2. In FIG. 1, the shelf support part 22 and the outlet part 21 on the left side as viewed from the front side of the refrigerator 1 are shown. The shelf support part 22 and the outlet part 21 on the right side as viewed from the front side of the refrigerator 1 are not shown.

  In FIG. 1, a substantially T-shaped air passage (shelf support portion 22 and outlet part 21) is shown as viewed from the side, but a shelf support portion (not shown) that supports the food storage shelf 12 or the food storage shelf 14. Alternatively, an air path may be formed to form an inverted L-shaped or L-shaped air path.

  By setting it as such a structure, compared with what blows off cold air only from the back surface of the refrigerator compartment 2, the temperature distribution in the refrigerator compartment 2 can be made uniform.

  FIG. 2 is a partially enlarged view of the left side surface in the refrigerator compartment 2.

  FIG. 3 shows the detailed shape of the outlet part 21. The material of the outlet part 21 is, for example, ABS resin. The outlet part 21 has an elongated shape as a whole. A plurality of outlets 21a are formed in the longitudinal direction (six in the example of FIG. 3). Further, a plurality (four in FIG. 3) of engaging claws 21b are provided and engaged with a blowout port component attaching member 23 described later. The outlet part 21 and the outlet part attachment member 23 constitute an outlet duct.

  FIG. 4 shows details of the outlet part mounting member 23. The material of the outlet part mounting member 23 is also ABS resin. Since the outlet part 21 and the outlet part attachment member 23 form an outlet duct, the outlet part attachment member 23 has an elongated shape like the outlet part 21. A boss portion 23 a having a hole is formed at substantially the center of the outlet part mounting member 23. Moreover, the engagement piece 23b engaged with the inner box 1a is provided in the longitudinal direction both ends. The outlet part mounting member 23 is fixed to the inner box 1a by fixing the boss portion 23a to the inner box 1a with a screw and engaging the engaging piece 23b with the inner box 1a. Furthermore, the same number (four in FIG. 4) of engagement holes 23c with which the engagement claws 21b of the outlet part 21 are engaged are formed.

  The outlet part 21 is not directly fixed to the inner box 1a, but is fixed to the outlet part attachment member 23 by engagement. Therefore, the outlet part 21 can be removed as necessary.

  As shown in FIG. 5, part of the cool air that has exited the cooler chamber 18 flows through the rear duct 31, and is divided from the middle of the rear duct 31 to enter the air path of the shelf support portion 22. The air flows from the air path of the shelf support portion 22 to the air outlet duct 30, and cold air is blown out from the air outlet 21 a of the air outlet part 21 toward the refrigerator compartment 2 and the refrigerator compartment door 6 from the front surface of the refrigerator compartment 2.

  FIG. 6 is a side view of the refrigerator compartment as seen from the back side of FIG. The shelf support portion 22 is viewed from the inner box 1a side. The back side (inner box 1a side) of the outlet part mounting member 23 of the outlet duct 30 connected to the shelf support portion 22 is visible. The cold air diverted from the rear duct 31 passes through the air passage 22 a of the shelf support portion 22, enters the outlet duct 30, and blows out to the refrigerator compartment 2.

  As shown in FIG. 7, the shelf support portion 22 is configured to be retracted into the back side of the air outlet duct 30, that is, the back side of the air outlet part mounting member 23. Since the outlet part mounting member 23 is fixed to the inner box 1a, the shelf support part 22 can be inserted into the back side of the outlet part mounting member 23 to support the shelf without using a fastening part such as a screw. The part 22 can be fixed.

  Further, as already described, since the outlet part 21 is fixed to the outlet part attachment member 23 by engagement, the outlet part 21 can be removed.

  As described above, since the shelf support portion 22 can be fixed without using fastening parts such as screws, the assembly workability can be improved and the parts price can be reduced.

  Further, the outlet part 21 can be removed from the outlet part attaching member 23 and can be cleaned.

  For example, the design of the refrigerator compartment can be improved by painting the outlet part 21 in a metallic style.
